Abstract
Official abstract text for this publication.
To provide a dental porcelain paste which can maintain maintaining the paste state and have excellent application property for a long period of time and hardly causes carbonization or bubbles due to the influence of an organic component or a polymer component during firing. The present invention provides a dental porcelain paste for preparing a dental prosthesis device, comprising: 50.0 to 80.0 wt. % of a glass powder (a) having a maximum particle diameter of 100 μm or less and an average particle diameter of 1 to 20 μm, 0.5 to 10.0 wt. % of a hydrophobized fine particle silica (b) having an average primary particle diameter of 1 to 50 nm, and 10.0 to 49.5 wt. % of an organic solvent (c) having a boiling point it is within (bp) of 100 to 300° C.
